Okla. Stat. tit. 43, § 43-103: Venue for any action for divorce, annulment of a marriage

or legal separation.

A. The venue of any action for divorce, annulment of a marriage

or legal separation may be in the following counties:

1. An action for divorce or annulment of a marriage may be

filed in the county in which the petitioner has been a resident for

the thirty (30) days immediately preceding the filing of the

petition or in the county in which the respondent is a resident;

provided, the action may be assigned for trial in any county within

the judicial district by the chief judge of the district; and

2. An action for legal separation may be brought in the county

in which either party is a resident at the time of the filing of the

petition.

B. The court may, upon application of a party, transfer an

action for divorce, annulment of marriage or legal separation at any

time after filing of the petition to any county where venue would be

proper under subsection A of this section if the requirements of

subsection C or D of this section are met.

C. The court shall grant a party’s application for change of

venue when the other party is not a resident of this state at the

time the application for change of venue is filed, or the plaintiff

has departed from this state and has been absent for more than six

(6) months preceding the date the application for change of venue is

filed, and transfer is requested to the county where the applying

party resides in this state.

D. The court shall grant a party’s application for change of

venue when the court determines that it is an inconvenient forum

under the circumstances and the court in another county is a more

appropriate forum consistent with the factors in subsection B of

Section 551-207 of the Uniform Child Custody Jurisdiction and

Enforcement Act after substitution of the word "county" for the word

"state" in such section of the act, and transfer is requested to the

county where the applying party resides in the state.
